Defining the Problem - Why is a non-invasive intracranial pressure monitor needed?
The monitoring of intracranial pressure and pressure volume index is of significant diagnostic and post-operative importance for many patients with cranial injuries and for patients who have undergone brain surgery. Cranial injuries often affect the pressure of the subarachnoidal fluid around the brain. Abnormally elevated intracranial pressure (ICP) occurs in about 60% of patients with head trauma. When ICP increases above 20mmHg, a 95% death rate occurs. High ICP reduces blood flow to the brain, preventing oxygen and nutrients from reaching brain tissue. This starvation results in the death of brain tissue
